That torque figure drops to 10.17 N·m at 3500 rpm — the constant-power region starts above base speed, so the load's torque demand at high speed must stay within that envelope. Continuous stall torque is 18.5 N·m at 16.83 A stall current — this is the holding torque at zero speed, useful for indexing or vertical-axis applications where the load must be held at rest without a brake. ## Feedback and connectivity — encoder type and cable routing Single-turn SinCos Hiperface encoder provides absolute position feedback over one revolution — the drive knows the rotor angle at power-up without a homing move, as long as the application stays within one turn. For multi-turn applications, a different encoder variant or external homing is needed. Rotatable right-angled connectors let the power and feedback cables exit in any of four orientations — useful when the motor is mounted in a tight cabinet or against a machine frame where straight connectors would interfere. ## Mechanical fit — flange, shaft, and mounting dimensions 140 mm flange with a 130 mm centring collar and four 11 mm mounting holes — this is the standard IEC B5 (FF) flange pattern for motors in this power class. The 24 mm shaft with a parallel key and 50 mm shaft length couples to most standard gearboxes and pulleys. Overall length is 192 mm (7.6 in) — compact for a 3.7 kW motor, but account for the connector protrusion when laying out the enclosure. No second shaft end, so no provision for a separate encoder or tachometer on the rear. Maximum radial force at the shaft is 2240 N at 1000 rpm, dropping to 1550 N at 3000 rpm — belt-drive applications must stay within these limits to avoid bearing overload. ## Thermal management — natural convection and winding protection Natural convection cooling — no internal fan, so the motor relies on ambient airflow and the mounting surface for heat dissipation. In a still-air cabinet or at low speeds, the duty cycle must be derated; the stator resistance is 0.23 Ω and inductance 2.99 mH, so I²R losses at 16.83 A stall current are about 65 W. Maximum winding temperature is 135 °C (275 °F) hot-spot — the torque constant is specified at 120 °C (248 °F), so expect some torque drop if the motor runs near its thermal limit. The back-EMF constant is 70.7 V/krpm, which sets the bus voltage needed to reach rated speed. No holding brake on this variant. If the application requires a brake for vertical-axis holding or emergency stop, specify the brake-equipped version of this frame size. The motor mates with Lexium 52 or 62 drives — the nominal speed and torque curves are listed for both drive families at various supply voltages.","metaTitle":"Schneider Electric MH31402P11A2200 Servo Motor, 3.73 kW","metaDescription":"Schneider Electric MH31402P11A2200 servo motor, 3.73 kW continuous power, 16.34 N·m nominal torque, IP65, single-turn SinCos Hiperface encoder.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","Length":"7.6 in (192 mm)","Category":"US1PC5218359","Key width":"0.3 in (8 mm)","Shaft end":"Parallel key","Encoder type":"Single turn SinCos Hiperface","Second shaft":"Without second shaft end","Shaft length":"2.0 in (50 mm)","Holding brake":"Without","Nominal speed":"1000 rpm LXM52 14.87 mA, 115 V, single phase 2000 rpm LXM52 13.13 mA, 230 V, single phase 3500 rpm LXM52 9.76 mA, 400 V, three phase 3500 rpm LXM52 9.76 mA, 480 V, three phase 1000 rpm LXM62 14.87 mA, 115 V, single phase 2000 rpm LXM62 13.13 mA, 230 V, single phase 3500 rpm LXM62 9.76 mA, 400 V, three phase 3500 rpm LXM62 9.76 mA, 480 V, three phase","Rotor inertia":"32 kg.cm²","Nominal torque":"144.62 lbf.in (16.34 N.m) LXM52 14.87 mA, 115 V, three phase 123.9 lbf.in (14.0 N.m) LXM52 13.13 mA, 230 V, single phase 90.01 lbf.in (10.17 N.m) LXM52 9.76 mA, 400 V, three phase 90.01 lbf.in (10.17 N.m) LXM52 9.76 mA, 480 V, three phase 144.62 lbf.in (16.34 N.m) LXM62 14.87 mA, 115 V, single phase 123.9 lbf.in (14.0 N.m) LXM62 13.13 mA, 230 V, single phase 90.01 lbf.in (10.17 N.m) LXM62 9.76 mA, 400 V, three phase 90.01 lbf.in (10.17 N.m) LXM62 9.76 mA, 480 V, three phase","Shaft diameter":"0.9 in (24 mm)","Torque constant":"1.1 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"3730 W","Mounting Support":"International standard flange","Sizing reference":"MH31402P","Back emf constant":"70.7 V/krpm","Device short name":"MH3","Motor flange size":"5.5 in (140 mm)","Peak stall torque":"491.2 lbf.in (55.5 N.m), 115...480 V, three phase","Stator inductance":"2.99 mH","Stator resistance":"0.23 Ohm","Maximum current Irms":"57.42 A","Nominal output power":"1.71 W, 115 V 2.93 W, 230 V 3.73 W, 400 V 3.73 W, 480 V","Centring collar depth":"0.1 in (3.5 mm)","Electrical Connection":"Rotatable right-angled connectors","Nbr. of units in pkg.":"1","Number of motor poles":"10","Temperature copper hot":"275 °F (135 °C)","Continuous stall torque":"163.7 lbf.in (18.5 N.m), 115...480 V, three phase","IP Degree of Protection":"IP65 standard","Maximum radial force Fr":"2240 N 1000 rpm 1780 N 2000 rpm 1550 N 3000 rpm","Mounting holes diameter":"0.4 in (11 mm)","Centring collar diameter":"5.1 in (130 mm)","Continuous stall current":"16.83 A","Maximum mechanical speed":"4000 rpm","Number of mounting holes":"4","Product or Component Type":"Servo motor","Speed feedback resolution":"128 periods","[Us] rated supply voltage":"115...480 V","Stator electrical time constant":"13 ms","Circle diameter of the mounting holes":"6.5 in (165 mm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/99b1f0ce06f6166915f55cdb69e61baf.pdf","sourceUrl":"https://www.se.com/ie/en/product/MH31402P11A2200/mh3-servomotor-140mm-2-stacks-keyed-shaft-sincos-singleturn-128-no-brake-angular-ip65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/MH31402P11A2200/alternatives.json"},"ai":{"faq":[{"question":"What is the nominal torque of MH31402P11A2200 at different speeds?","answer":"Nominal torque is 16.34 N·m at 1000 rpm and 10.17 N·m at 3500 rpm, depending on the supply voltage and drive model.
